FILLER.

' Application filed April 1, 1024. Serial 10.10am

.in operating the owper apparatus and Sie.

mens regenerative gas furnace.

The su eri or features of the invention are obtained y imparting to the filler a certain definite form so as to ofier the largest possible surface topassing gases. The form, of the individual fillers comprises a substantially cylindrical body, the cross section of which resembles a fi 8. This brick may also be provide through the entire depth of it or its surface may be chequered. The brick fillers thus r obtained are then simply thrown intothe Cowper apparatus or any other heat accumulator without the least regard 'for their arrangement within the apparatus.

I am aware that prior to my invention fillers for Cowper apparatus and the other with holes passing.

kinds of heat accumulated mentioned above have been known; these'fillers however, re-

quired careful building up within the apparatus. v

'. The drawings illustrate two modifications 86 v of such bricks which consist either of ceramic sinter mass or acidproof metals, accor'ding to requirements.

ig. 1 is a erspective view of my preferred form 9 brick.

Fig. 2 is a perspective view of a modified form of brick;

' As the illustrations show, the basic-form of the brick is a substantially cylindrical body. The two opposite edges 1 are bufied,

while the two other edges 2 are cut in an in ward direction. The brick has now the form of an 8. Eventually drills 3 maivhbe pro-, vided to run through the bricks. e bricks thus obtained are thrown irregularly into the apparatus.

I claim: .A refractory filler element of the type adapted to be promiscuously thrown into heat accumulators, consisting of a substantially cylindrical body, the cross section of which resembles a figure 8. g

In testimony whereoflhave aflixed my signature. v l
